Product Description
On April 14, 1861, following the 
surrender of Fort Sumter, Washington was "put into the condition of a 
siege," declared Abraham Lincoln. Located sixty miles south of the 
Mason-Dixon Line, the nation's capital was surrounded by the slave 
states of Maryland and Virginia. With no fortifications and only a 
handful of trained soldiers, Washington was an ideal target for the 
Confederacy. The South echoed with cries of "On to Washington!" and 
Jefferson Davis's wife sent out cards inviting her friends to a 
reception at the White House on May 1. 
Lincoln issued an 
emergency proclamation on April 15, calling for 75,000 troops to 
suppress the rebellion and protect the capital. One question now 
transfixed the nation: Whose forces would reach Washington first: 
Northern defenders or Southern attackers?
For 12 days, the city's
 fate hung in the balance. Washington was entirely isolated from the 
North--without trains, telegraph, or mail. Sandbags were stacked around 
major landmarks, and the unfinished Capitol was transformed into a 
barracks, with volunteer troops camping out in the House and Senate 
chambers. Meanwhile, Maryland secessionists blocked the passage of Union
 reinforcements trying to reach Washington, and a rumored force of 
20,000 Confederate soldiers lay in wait just across the Potomac River. 
Drawing on firsthand accounts, The Siege of Washington
 tells this story from the perspective of leading officials, residents 
trapped inside the city, Confederates plotting to seize it, and Union 
troops racing to save it, capturing with brilliance and immediacy the 
precarious first days of the Civil War. 
Happy Reading!  ;-)
